3. Identify the reason for the malfunction and correct it before restarting the system.

DisposalDispose of equipment and materials used in operation and servicing according to local codes.




Equipment-Specific Safety InformationThe following safety information is specific to the Nordson EFD Toµch controller.

Intended Use

• This equipment is for indoor use only.

• Use the Toµch controller only in conjunction with its associated power cable and, if needed, its associated extension cable.

• Do not open the Toµch controller.

Unintended Fluid Release

• Prior to initial operation, check to see if fluid flows out of a valve that is turned off even when no fluid pressure is being applied. If this occurs, it may be because the fluid reservoir is positioned higher than the valve, in which case hydrostatic pressure causes the fluid to flow out of a valve that is not closed. Position the fluid reservoir low enough such that no fluid leaks from the valve when the valve is shut off.

• In the case of damage to the piezo actuator or the Toµch controller, the valve may transition from a CLOSED to an OPEN condition, which can cause fluid release. Nordson EFD recommends continually monitoring the status signal of the Toµch controller and immediately and automatically bleeding the fluid reservoir if these signals indicate an error.

• Before connecting or disconnecting a valve cable, release fluid pressure and disconnect and lock out power to the Toµch controller.

Install the Valve and ControllerThe callouts in the system installation images correspond to the steps in this procedure.

1. Install any components other than the Pµlse valve and controller that will comprise the complete dispensing system. For example, if you are using a fluid reservoir, position and install all the fluid reservoir components. For all ancillary components, refer to the quick start guide and / or operating manual provided with those components for installation, setup, and operating instructions.

CAUTIONEnsure that air can flow around the controller. Blocked air flow can cause overheating.

2. Install or position the Toµch controller. The controller can be integrated into existing machinery or used as a tabletop device:

• To integrate the controller into existing machinery, remove the feet (if needed) and use the following specifications to install it as a standard rack mount: - Height: 3U - Width: 28 Hp - Depth: for 160 mm (6.3")

• To use the controller as a tabletop device, lower the hinged legs.

• Ensure there is adequate air flow around the controller.

3. Connect power to the controller as follows:

a. Connect the power cable to the back of the controller and to your local power source observing the following guidelines:

• Use only the supplied power cable and power supply.

• Ensure that the power source is located near the equipment and is easily accessible.

• Use only on a circuit with a fuse or circuit breaker that is 20 Amp or less.

b. Connect a 16 AWG (1.3 mm) ground wire to the chassis grounding screw on the rear of the chassis using a toothed grounding lug. The wire must have green insulation with a yellow stripe or must be non-insulated (bare).

c. Attach the opposite end of the ground wire to a permanent earth ground using toothed washers or a toothed lug.

Install the Valve and the Controller (continued)

CAUTIONAlways switch OFF the Toµch controller before connecting or disconnecting the valve. Failure to do so can damage the controller and the valve.

4. Assemble and mount the Pµlse valve as follows:

a. Open the hinged seat of the piezo actuator by pushing the latch pin back towards the valve.

b. Insert the fluid body assembly and close the hinged seat, ensuring it is fully engaged.

c. Referring to the guidelines below, install the Pµlse valve on the dispensing equipment:

• Nordson EFD strongly recommends using a valve mounting bracket. There are multiple mounting holes to allow for adjustment. Some valve mounting examples are shown below.

• For repeatable mounting-location precision, use alignment dowels to mount the valve by the frame side.

• When mounting the valve, do not install bracketing that could apply pressure to either side panel. Doing so can damage the piezoactuator, compromising valve performance.

• When mounting a Pµlse XP valve, ensure that the fluid supply feed loads are properly supported to prevent movement of the fluid body assembly.

NOTE: Valve mounting kits are available. Refer to the valve operating manual.

Do not exceed the maximum extension cable length of 9 m (30 ft). Doing so will adversely affect communication between the valve and the controller.

CAUTION

d. Connect the valve power and communication cables to the connectors on the back of the Toµch controller. Refer to “Valve Extension Cables (Standard Toµch Controller)” on page 47 for available extension cables.

NOTE: The VALVE power and communication ports differ on the Toµch XP controller, so different valve extension cables are required. For Toµch XP controller extension cables, refer to “Toµch XP Valve Extension Cables” on page 74.

e. To divert static charges from the valve, connect it to the machine system ground. Vacant fastening threads may be used for this.

f. Add the fluid supply, but do not pressurize the fluid supply at this point.

NOTE: For low viscosity fluids used in a syringe barrel application, fill the barrel after installing it on the fluid-inlet fitting. High viscosity materials can be loaded into the barrel before installing it on the inlet fitting.


55. Connect inputs / outputs (I/O) to I/O 1 and I/O 2 as needed for your operation. Refer to “Input / Output Port Pin Descriptions” on page 52 for detailed I/O information. A 15-position D-sub and backshell are provided. A cable for the 25-pin D-sub connection is customer-supplied.

NOTE: Nordson EFD recommends using the analog temperature output (I/O 1, pin 11) to provide operators with appropriate identification and protection against contact when the valve temperature exceeds +45° C (113° F).

Button or Icon Description

MODE Sets the system operating mode.

Mode Description

Timed In the Timed mode, the valve cycles according to the settings for PULSE (valve open time), CYCLE (time between deposits), and COUNT (number of deposits) for each valve initiate signal.

Continuous In the Continuous mode, the valve cycles according to the settings for PULSE (valve open time) and CYCLE (time between deposits) for as long as the valve initiate signal is active, ignoring any setting for COUNT (number of deposits).

NOTE: If the system is latched on to a signal in the Continuous mode, you cannot change screens.

External In the External mode, the controller operates as a slave to an input signal and thus no longer generates the timing signals required to drive the valve. This mode is typically used with a device such as the PICO 2+2-XCH-V3 controller for pattern generation.

NOTE: This selection is available only when SHOW VALVE EXTERNAL is toggled ON via the SYSTEM screen. Refer to SHOW VALVE EXTERNAL under “SYSTEM Screens” on page 32.

CAUTIONBecause the controller does not generate timing signals in the external mode, take care to not exceed the maximum operating parameters of the connected valve. In addition, the time setting of any external signal used to drive the valve must be greater than the RAMP OPEN profile time setting (refer to “WAVE PROFILE Screen” on page 27). Exceeding timing and valve operational parameters can result in overall loss of performance.

PULSE Sets how long the valve opens (in milliseconds).

Default: 10 (ms) Range: Depends on the open profile time and the type of valve being used; as low as 100 µs

possible

CYCLE Sets the amount of time between deposits (in milliseconds).

Default: 30 (ms) Range: 2 (ms) to 9.9999 (s) typical (minimum setting depends on open and close profile times)

SERVICE Nordson EFD use only.

Show STACK Temp.

When SHOW STACK TEMP is toggled on, the controller displays the actual temperature of the piezo actuator stack on the VALVE screen. When SHOW STACK TEMP is toggled off, the stack temperature is not displayed.

NOTE: This setting becomes useful when the valve is operating at the higher end of its operating range. Stack temperature is a crucial variable that can cause the controller to generate an alarm as it tries to protect the valve. For example, if an SD valve is running at a high frequency, the stack temperature increases. Once the stack temperature reaches 55° C (131° F), the controller generates an alarm because the valve temperature is getting too hot.

PASSWORDS Opens the SET CONTROL PASSWORD screen, which provides access to the password setup options. Refer to “Managing Password Protection” on page 40 for additional information.

Appendix A, Remotely Operating the ControllerYou can operate the controller through a personal computer (PC) using the supplied USB communication cable or by connecting to the RS232 connection through the 25-pin D-sub (port I/O 2). Communicating in this manner allows you to modify dispensing parameters remotely and also to load custom wave profiles on the controller.

Connection Using a PC

Connect the USB cable to the USB port on the back of the controller and to a PC.

Connection Using RS232

The 25-pin D-sub (port I/O 2) is configured for use with a null modem cable. Alternatively, use the I/O 2 port RS232 pins (pins 2 and 3) to make your connection. Refer to “I/O 2 25-Position D-Sub” on page 54 for the I/0 2 port pin descriptions.

Communication Specifications

The controller acts as a terminal to the remote host PC. The controller communicates using the following settings:

• Synchronous mode: half duplex

• Baud rate: 115200

• Start bit: 1

• Data length: 8 bit (ASCII)

• Parity bit: None

• Stop bit: 1

Communication Sequence

The host machine initiates all communication sequences. The controller evaluates the last four characters in the command packet as the command.

Typical Command Packet: xxxCCCC (where xxx is the setting and CCCC is the command)

The length of the setting varies depending on the command.

Serial Commands

Commands are evaluated after a return (Enter key or 0x0D hex). After a return is received, the controller evaluates the command, transmits any data related to the command, and closes the packet with <3.

The following tables provide the commands for the controller. Each entry includes a brief description of the command, shows the command format, and provides a description of the data that is attached and retrieved by the command.

NOTES:

• The <3 acknowledge command is removed from the examples since all commands are successfully evaluated.

• The return constant (Enter key: ↵) is depicted as [Enter] in all examples.

Appendix B, Toµch XP ControllerThe PICO® Toµch™ XP (Extreme Precision) controller and PICO Pµlse® XP jet valve apply the most exact fluid deposits, regardless of external factors that can affect deposit definition and repeatability. The system’s closed-loop capability monitors variables such as temperature and internal tolerances, allowing self-adjustment to minimize the production downtime needed to recalibrate the jetting system when external factors cause slight variations in repeatability. This is especially important for applications that require extremely precise, repeatable micro-deposits where strict tolerances or deposit definition must be met. The PICO Toµch XP controller allows users to program stroke in microns for the finest parameter adjustments possible.

The differences between the Toµch XP controller and the standard Toµch controller include the following:

• A 5-pin VALVE power cable instead of a 3-pin cable

• A 6-pin VALVE communication cable instead of a 5-pin cable.

• On the RAMP screen, STROKE is adjusted in microns (instead of the total percent of CLOSE VOLTS); the micron setting affects the tappet displacement. The ability to minutely adjust the tappet displacement contributes to the high deposit repeatability provided by the Toµch XP controller.

• On the Toµch XP VALVE screen only, the frequency indication displays under the cycle time.
